| CALPUFF Modeling Information for VISTAS BART Applications (3/16/2006)
VISTAS version of the CALPUFF model system (exit to Earth Tech web site)
Once at the Earth Tech web site, click on “download” located on the left side of the page. This takes you to a registration page that you may fill in or skip. Once completed or skipped, you reach a page that includes the “VISTAS – Recommended Version for BART Modeling”. The model can be download for free. Also located on the Earth Tech webpage is an example application of the CALPUFF modeling system for a model plant with instructions for model configuration. Ozone data is also provided. Ammonia data for use in the Ammonia Limiting Method will be posted when available later in spring 2006.
CALMET data files: Please contact your state modeling representative to obtain the 2001-2003 CALMET data for either the 12 km or 4 km datasets. Note: These are large data files (~135 GB for the 12 km data, and up to ~280 GB for a single domain of 4 km data). Please provide your state representative with an appropriately sized external hard drive.
MM5 meteorological model outputs for 2001, 2002, and 2003 were used to develop the 2001, 2002, and 2003 CALMET data files. The model performance documents for the MM5 runs are linked below.

VISTAS states are responsible for determining if a source may use the new IMPROVE equation in the BART exemption modeling. VISTAS contracted with Dr. Ivar Tombach to develop a post processor to allow CALPOST outputs to be used with the new IMPROVE equation. Dr. Tombach also provided instructions how to apply the post processor. VISTAS is providing access to the post processor and instructions for its application on the VISTAS website, but VISTAS does not have a policy position on the application of the post processor for the new IMPROVE equation. A BART source in a VISTAS state needs to obtain permission from the state to use this post processor. A BART source in a non-VISTAS state needs to contact their state to determine if the state would consider the new IMPROVE equation for BART.
